Module store 

Persistence.

The execution_events table is the source of truth. workflow_executions is a projection kept in the same transaction for fast listing. Every batch of events is appended atomically together with the projection update.

Two backends share the schema and the guarantees:

• SQLite (default): a single file, WAL mode, synchronous=FULL.
• PostgreSQL: pass a postgres:// URL. All statements run on one dedicated connection thread, so the synchronous engine never blocks the async server runtime from inside it, and the connection is re-established automatically if it drops.

PgMode

How a PgStore may write. Single-node servers use ReadWrite; the cluster mode (orbit server --cluster, see crate::cluster) gives a standby a ReadOnly store and the leader a Fenced one.
